Weird clunk sound and feel through throttle lift off and gear shift

[theaussieracer]

I recently bought a 2010 RCZ 200PS with 143,000km. Only a couple of days into driving it (admittedly pretty hard compared to how I'd normally drive a car) it started to develop an issue where I would shift from 1st, 2nd and 3rd (downshifts as well) and there'd be a weird clunk sound and feeling through the throttle and clutch pedal, and then when lifting off throttle it jerks forwards (especially in 2nd and 3rd gear). It is quite audible when there is no music playing. I suspect it is worn engine mounts however I would like to get some advice from the forum. Thanks

Potentially the rear engine mount, but I might be inclined to change all mounts, inc gearbox as they are all same age after all.
I believe they were born to be driven with a bit of gusto so get em changed and roar on.

Have the front suspension arms and the strut top mounts checked too while the works are being done.
